Misconceptions in Physics and Astronomy

STUDIO PHYSICS
AT THE UNIVERSITY OF
ALABAMA
Supported by the US Dept. of Education and The University of
Alabama
Statement
of the Problem
Traditional physics course:
3
lectures per week
1 laboratory (separate)
Large size
Issues
with Traditional Lecture
Inactive
learning
Poor attendance
Lack of coordination of labs/lectures
Inefficient use of technology
Impersonal
The
studio approach is:
Integrated
lecture/labs
Active learning
Technology
Almost daily assignments
Group work (mostly)
STUDIO IS ALSO:
 Flexible
 Adapts
to instructor’s tastes, styles
 Adapts to students’ needs
 Only
a structure
A LITTLE HISTORY

Foundation Coalition (NSF: Engineering)
 Active
Learning
 Technology in the classroom
 Teaming
 More technology in labs
DETAILS
Schedule: 2hrs, 2 days a week; 1 hr recitation
per week
 Short lectures
 Labs and activities for most of the 2-hr
sessions
 50-60 students per section
 Technology driven

Studio Physics Classroom
The University of Alabama
Department of Physics and Astronomy
Students in Studio Physics Classroom doing optics experiment

The
faculty role
Professor:
lectures, guides
GTA: guides, leads recitation
section
UTA: guides
Student/teacher
ratio: 20/1
LABS
 Take
data electronically
 Analyze data numerically
 …But also do paper/pencil analysis
WHAT GOES ON IN A 2-HOUR CLASS?
Some lecture
 Problem-solving examples
 Clicker questions
 Exercises
 Simulations
 Labs once a week

DO YOU COVER EVERYTHING?
No
 Must pick and choose
 Cover main items well
 Students responsible for rest
 This is a 4-hour course!

MISCONCEPTIONS
Students have preconceived ideas
 These are hard to dislodge
 People can hold conflicting concepts
simultaneously
 Students must be confronted by a conflict in
order to abandon a misconception

 More
than once
EXAMPLE
Consider a boat loaded with scrap iron in a
swimming pool. If the iron is thrown overboard
into the pool, will the water level at the edge of
the pool
A. rise,
B. fall, or
C. remain unchanged?

WHAT WE KNOW
Interactive engagement techniques outstrip
“traditional” in conceptual learning
(Hake,1997)
 Conceptual learning in mechanics often
measured with Force Concept Inventory
(Hestenes et al., 1992, 1995)
 Hake gain: g = (post – pre)/(100% - pre)

HAKE’S RESULTS
STUDIO FORMAT ALONE DOES NOT
GUARANTEE CONCEPTUAL LEARNING
Cummings et al. (1999): Interactive Lecture
Demonstrations (Sokoloff and Thornton,
1997) and Cooperative Group Problem
Solving (Heller et al., 1992) are effective in a
studio context.
 Many of Hake’s examples of interactive
engagement were lecture courses

OBSERVATIONS
Hake (1998): Students won’t take seriously
tasks they don’t get credit for.
 Students are not necessarily actively (or even
inactively) engaged when we think they are.
